Pedestrian crossing system has figure to create visual warning and an audio warning system, both with sensors to control that they are working and to cut off electricity supply to either warning if failure in either warning is detected

摘要

The system (1) comprises a figure (2) placed over a lamp to create a light signal and an audio system (3) to create a sound signal. Both systems are fed by the same supply (5) from the intersection controller (4). There are sensors for controlling that the light and audio signal are working and disabled the electricity supply of both if either system has a failure.
